生活中那些见面不打招呼者常被认为是生性懒惰或冷漠。但是,德国的一个研究小组发现,这种情况更可能是因为他们天生难以分辨人脸的缘故。最近的研究成果表明:这是由一种遗传病引起的。在美国平均每五人就有一人患有这种遗传病。脑扫描结果显示,他们的颞叶和枕骨叶存在缺陷,而这两个部位都和人脑的识别功能密切相关。 Those who meet in the life without greeting are often considered lazy or indifferent. However, a German research team found that this situation is more likely to be due to their inherent difficulty in distinguishing faces. Recent research shows that this is caused by a genetic disease. One in every five people in the United States suffers from this genetic disease. Brain scans show that there are defects in their temporal lobe and occipital lobe, both of which are closely related to the recognition function of the human brain.
